25 A sound footing for learning
Schools are hubs of learning, yet the effectiveness of teaching depends on an often- overlooked factor. Michael Anderson of Zentia discuss the how the acoustic environment is crucial for optimal education, and the guidance available
T
he quality of sound within a classroom can significantly impact the learning experience of both students and educators. Inadequate acoustics can lead to a noisy classroom, negatively affecting student’s attitudes, behaviours and retention rates. It can even take a toll on the teacher’s
health. That is why it is important that government guidelines exist to enhance acoustic building design, including the Building Bulletin 93 (BB93).
The importance of good acoustics In a classroom where the teacher’s voice is drowned out by a range of outside noises such as footsteps, whispers and distant chatter, it becomes challenging for students to focus on lessons. Even when a classroom is quiet, a teacher may have to talk louder to ensure their voices travel to the back of the classroom if there is an imbalance in acoustics. The quality of the sound environment plays a pivotal role in the educational journey, affecting both students and educators alike.
Numerous studies have illuminated the link between classroom acoustics and student engagement. When students struggle to hear teachers due to excessive background noise, their ability to concentrate diminishes, leading to a lack of participation, enthusiasm and an overall negative attitude towards learning. Sadly, not being able to hear and therefore retain information in a classroom can also lead to a decline in academic performance, and failure to grasp fundamental concepts. The impact also extends beyond engagement. Studies have also shown that students in noisy classrooms are more likely to display disruptive behaviour, and the frustration of not being able to hear clearly can lead to restlessness, bad behaviour, and disciplinary issues.
It is not just students who bear the brunt of inadequate classroom acoustics; teachers can also pay a price. As noise

levels increase, teachers may experience heightened stress levels. The constant effort to make oneself heard the most can lead to vocal strain, fatigue, and frustration. These stressors can manifest in physiological responses such as an increased heart rate, which, if chronic, can contribute to more severe health problems like hypertension and heart disease.
Government guidance
Recognising the importance of acoustic design in educational settings, the UK Department of Education has provided invaluable guidance through Building Bulletin 93 (BB93). This comprehensive document outlines the specific acoustic standards and recommendations for the design of new and refurbished school buildings, focusing on how to achieve adequate acoustic performance. BB93 covers various aspects, including classroom design, building materials, sound insulation, reverberation control, and the
